Patent number: 7607914Abstract: A combustion type waste gas treatment system capable of oxidatively decomposing a hazardous combustible waste gas while heating efficiently with a structure which allows the waste gas to mix with an auxiliary burning gas efficiently without the occurrence of backfire in a waste gas inlet pipe. The combustion type waste gas treatment system has a burner part and a combustion chamber. Combustion flames are formed to extend from the burner part toward the combustion chamber, and a combustible waste gas is introduced into the combustion flames from waste gas inlet pipes thereby oxidatively decomposing the waste gas. A flow velocity accelerating device makes the flow velocity of the combustible waste gas flowing through the waste gas inlet pipe higher than the burning velocity of the combustible waste gas.Type: GrantFiled: February 23, 2007Date of Patent: October 27, 2009Assignee: Ebara CorporationInventors: Tetsuo Komai, Kohtaro Kawamura, Takeshi Tsuji, Rikiya Nakamura, Kazutaka Okuda, Keiichi Ishikawa, Tomonori Ohashi, Yoshiro Takemura, Yasutaka Muroga, Tadakazu Nishikawa, Yuji Shirao
